Combined with photosensitive medicine, PDT can safely treat various kinds of skin problems, mainly covering the following aspects.

3. Repairing scar: using narrow-spectrum red, blue, green genomic biology light source, PDT can effectively function at the level of subcutaneous tissue, the mitochondria of which absorb the energy of the PDT.
